If I could get some of the aviation gas they used to use with the piston type aircraft engines, I'd use that as well.
You don't every want to try that on a car with a catalytic converter. I have my own plane that burns on 100LL Avgas (100 Octane Low Lead). People have asked me if they could put Avgas in their cars to make them run better. I advise them that Avgas will make their cars undriveable because of the lead contained in this fuel. Putting Avgas in a car will guarantee a ruined catalytic converter which I'm sure could get expensive.
